Dr. Nathan "Nate" Heywood, Oliver Queen and others in “Unfinished Business”

Thank you for not having me arrested back there. Those security guard really overreacted. You know, one of them tried to mace me?

Dr. Heywood, I only agreed to give you 5 minutes, which was 3 minutes ago, because Ray and Sara are friends of mine. I don't know the first thing about any Legends.

Nate

Of course you do, because you're the Green Arrow.

Excuse me? We're done here.

Nate

Look, I'm sorry, I didn't mean to drop a bomb on you like that. It's just that I've exhausted all my normal avenues, and you're the only person left who won't think I'm crazy.

You sure about that?

Nate

I'm a historian. I specialize in deductive historical reconstruction. In a layman's terms, I'm a time detective, which I really don't have to be to look at a calendar to see one week after you came to this city, Robin Hood showed up.
